The AD7828KPZ is a high performance analog to digital converter (ADC) designed specifically for industrial and commercial applications. This device offers a wide range of functions and features, such as eight channels of high-resolution, simultaneous sampling, high throughput rate, a large input voltage range, and buffer amplifiers. In addition, the AD7828KPZ is suitable for measuring a wide range of input voltages, from zero to ±16V,, due to its low-noise, differential-input architecture. This makes it suitable for a variety of tasks, from industrial and commercial sound and pressure measurements, to medical and avionics sensor measurements.

The AD7828KPZ performs accurate, noise free conversion of analog signals into digital form and is highly reliable and efficient. The AD7828KPZ has eight differential inputs which can be configured as single-ended inputs. The differential inputs provide high noise immunity as well as improved accuracy and balance for a wide range of sensors and applications. The inputs can be programmed with different offset and gain values which provide users with the flexibility to customize each input according to the application requirements.

The AD7828KPZ utilizes 12-bit resolution and achieves a conversion speed of 2.3µsec, allowing the ADC to keep up with faster sampling rates. The AD7828KPZ also provides a low power consumption (1.4 ± 1.0 mA in normal operation and 0.15 μA in standby mode) and a low-power mode which consumes a fraction of the power of a normal operation. This makes the AD7828KPZ a practical choice for applications that require high resolution and low latency.

The AD7828KPZ works by measuring the analog input voltages and converting them into digital form. The device uses a Charge Distribution Digital Converter (CDDC) architecture which eliminates the need for external components. An internal clock is used to trigger the sampling of the analog inputs, which has wide frequency range of 0.1Hz to 64kHz. The ADC then converts the analog voltage into a digital format, which can then be read by a microcontroller or other digital device. The output of the AD7828KPZ is a 12-bit digital word.

The AD7828KPZ is also capable of buffering the analog inputs, allowing for longer cables to be used without any signal degradation. It also offers multiplexer functionality for larger volumes of data, allowing multiple ADC channels to be sampled by a single clock. Additionally, the device includes a reference voltage source which can be used to set the output voltage of the ADC.

The AD7828KPZ is an ideal choice for a wide range of industrial and commercial applications, including sound and pressure measurements, medical and avionics sensor measurements, and general-purpose applications which require a high resolution, low latency measurement device. Its small form factor and low power consumption make it suitable for these applications, while its multiple input configuration and buffering capabilities allow for maximum flexibility.
